    ... SolarMagic Dual 5A Compound Gate Driver General Description The SM72482 Dual Gate Driver replaces industry standard gate drivers with improved peak output current and efficiency. Each “compound” output driver stage includes MOS and bipo- lar transistors operating in parallel that together sink more than 5A peak from capacitive loads ...

    ... CC EE proximately 3.0V. The SM72482MY –1 device hold both outputs in the low state in the under-voltage lockout (UVLO) condition. The SM72482MA–4 has an active high output state of OUT_A during UVLO. When VCC is less than the UVLO threshold voltage, OUT_A will be locked in the high state while OUT_B will be disabled in the low state. This configuration allows the SM72482MY – ...

    ... GATE P = 12V 300 kHz = 0.108W. DRIVER If both channels of the SM72482 are operating at equal fre- quency with equivalent loads, the total losses will be twice as this value which is 0.216W. In addition to the above gate charge power dissipation, - tran- sient power is dissipated in the driver during output transi- tions ...
